COMPARISON OF GOLD SELECTIVE ION EXCHANGE RESINS AND ACTIVATED CARBON FOR THE RECOVERY OF GOLD FROM COPPERGOLD LEACH LIQUORS By 1Johanna van Deventer, 2Volha Bazhko and 2Volha Yahorava 1Purolite, South Africa 2Mintek, South Africa Presenter and Corresponding Author
In this paper one strong acidic, one strong basic and one weak basic ionexchange resins, considered as exhausted in an industrial demineralizing plant, are screened for gold recovery from cyanide solutions. Based on the observed ability for the recovery and on the ease of regeneration, the weak base anion exchanger Purolite A100 is selected.
Jul 01, 2016· Ion exchange resin technology is a costeffective option that meets purification needs across many food processing schemes with minimal limitations. ... Ion exchange resins offer better purification of processed foods ... Figure 1 illustrates the sharp separation achieved with a uniform particle size IER chromatographic in a smallscale ...
Elution and electrowinning of gold from goldselective strongbase resins Elution and electrowinning of gold from goldselective strongbase resins Conradie, ; Johns, ; Fowles, 00:00:00 The recovery of gold was investigated using the new goldselective resin, Minix, which was developed by Mintek. The most suitable elution technique for this resin was found to .
performed on the pregnant leach liquor prior to gold recovery could cause gold loss, especially if a high removal efficiency of copper cyanide is required prior to gold recovery. This paper discusses the use of a commercially available ion exchange resin with an exceptionally high selectivity for gold over copper.
From screening out magnetics to smallscale Dense Media Separator testing, ionexchange recovery to electowinning systems; Gekko''s other high quality products cover all aspects of energyefficient flowsheet design.
The adsorption of gold complexes onto the activated carbon is the basis of modern techniques for gold recovery. The next step is the recovery of adsorbed gold from activated carbon with an efficient eluant. ... Ion exchange technology may be used in the stripping gold cyanide from aqueous/organic solutions. 4. Conclusions ... ScienceDirect ...
Jul 13, 2017· This means that conventional ion exchange resins, solvent extraction or reduction and precipitation methods of precious metal recovery by adding chemical reagents are not economically attractive. Therefore, there is a strong need to develop and apply low‐cost and eco‐friendly methods to recover precious metals.
Nov 15, 2011· Anglo Asian Mining plc has selected the Mintekdeveloped DOWEX™ MINIX™ ionexchange resin for gold recovery at its Gedabek (Gädäbäy) goldcopper project in Azerbaijan. Gedabek, which is the first operating gold mine in the southwest Asian country, was officially opened and produced its first gold in May 2009.
Complementary Technologies. ... Ion Exchange (IX) processes allow for purification and concentration of targeted ions from solutions for selective recovery. ... The relatively simple operation of ion exchange on a small scale vs solvent extraction makes the technology ideally suited for rapid set up in small to medium sized operations.
Jan 06, 2015· Apex Engineering has designed several relatively smallscale treatment systems for sulfate removal from mine water (Table 2). ... Apex Engineering has incorporated ISSR as a component of the treatment systems for Kinross Gold and Veris Gold (Table 2). ... Ion exchange processes such as GYPCIX and SulfIX™ ...
Gold. Insitu leaching has not been used on a commercial scale for gold mining. A threeyear pilot program was undertaken in the 1970s to insitu leach gold ore at the Ajax mine in the Cripple Creek district in the US, using a chloride and iodide solution.
Operation of a smallscale resininpulp plant showed that gold could be recovered from a leach pulp to yield loadings of gold of up to 6000 mg L1 and loadings of copper below 100 mg L1. Under ideal conditions, the gold concentration in the barren pulp could contain less than mg L1.
Ion exchange method One method, which may offer promise for the future in the treatment of plating waste and recovery of valuable constituents, is the use of ion exchange material. This technology has the advantage that wastewater can be reused instead of using fresh water. The use of ion exchanger in wastewater technology required high cost.
Nutrient Recovery. Nitrogen and phosphorus will be recovered from the secondary effluent using ion exchange media. Phosphorus will be removed by adopting a hybrid ion exchange media (HAIX) for phosphorus removal and ammonia will be removed using Mesolite which is a type of zeolite.

Precious Metal Refining: Dore is a mixture of gold and silver typically containing less than 5% base metal exact composition varies widely depending on its source and processing history. Dore producers, in deciding whether or not to refine their dore, can custom design a .
In industrialscale, gold extraction is conducted by cyanidation process followed by carbon in pulp or ion exchange process. The solvents commonly used in the cyanidation process are NaCN, KCN, Ca (CN) 2, or a mixture of all three solvents. The simplest solvent used is NaCN because it can dissolve gold better than other solvents [4].
